I wouldn't compare a Pit Bull to a Venomous Snake. Is there the chance that a dog that size could kill a person? Absolutely. There is that chance with ANY dog. I bet a lot of people didn't hear about the Pom that killed the infant a few years back. Even small dogs can cause a lot of damage if they want to, even to adults. I will say Pits are not for everyone, and there are some people who should NEVER have one. But I think that comparing them to venomous snakes is a bit extreme, personally.
I have handled hundreds of dogs over the last 10 years, and the breed I have been snapped at the most I would have to say is the lab. And second is the chi.

llovelace - I love that picture And I agree that Pits are some of the most beautiful dogs out there.
